The Basics of Reciprocating vs. Centrifugal Pumps

engineering column PD pumps Understanding the differences between these types of pumps can mean avoiding difficulties and reliability problems.

The demand for the duties that fall within the performance range of reciprocating pumps is rising. Process flows are falling while the pressures required are increasing.

Engineers are generally familiar with operating principles, performance curves and selection criteria for centrifugal pumps, but the training and knowledge around the operating principles of reciprocating pumps is not as common.

Unlike centrifugal pumps, reciprocating pumps have a stronger interaction with the system within which they sit. This is due to the pressure pulsations they generate.

If we think about any linear reciprocating motion of a piston, at some point the velocity of the piston is zero as it changes direction at the top and bottom of its stroke. This means that the pressure pulsations are much larger in a reciprocating machine than in a centrifugal machine.

Asset Monitoring Improves Reliability & Visibility

Hydro remote condition monitoring A major pipeline transmission company found itself reconsidering the effectiveness of its maintenance strategy. The company faced a challenge: optimizing asset visibility and implementing remote condition monitoring of equipment health while avoiding a high-cost investment and installation disruptions.

This particular pipeline transfers a variety of products, ranging from gasoline to jet fuel, serving customers via pump stations and storage tanks across the United States. For this customer, it is imperative to ensure that pumping assets are efficient, reliable and safely maintained consistently. The pipeline supports the needs of more than 50 cities, thus making the pumping assets critical to the availability and overall operation.

Technology plays a vital role in day-to-day operations in supporting end user activities, ensuring strict safety regulations, optimizing maintenance and providing data on equipment health. In this case, the pipeline company wanted to significantly improve and innovate upon its current maintenance approach in two ways: by monitoring asset visibility in real-time and trending data for their critical pumping equipment.

CHICAGO – As Illinois’ unemployment rate continued to fall to its lowest point in six years, Governor Pat Quinn today visited Hydro, Inc. in Chicago to discuss the state’s ongoing economic recovery. Over the past six months, Illinois’ unemployment rate has fallen faster than any other state in the country. Illinois’ unemployment rate dropped for the sixth consecutive month, from 6.8 to 6.7 percent in August, its lowest level since August 2008 and lower than when the Governor took office. Today’s event is part of the Governor’s agenda to create jobs and drive Illinois’ economy forward.

“Hardworking women and men across our state are back on the job and today’s numbers are proof that Illinois’ comeback continues,” Governor Quinn said. “More people are working today than at any time in the past six years and that is thanks in part to companies like Hydro who are staking their future right here in the Land of Lincoln. While we have more work to do, we are getting the job done and Illinois is headed in the right direction.”

The Illinois unemployment rate fell in August for the sixth consecutive month to reach 6.7 percent while employers created 13,800 jobs, according to data released earlier today by the U.S. Bureau of Labor Statistics and the Illinois Department of Employment Security. This is the lowest rate since August 2008 and the drop from 9.2 percent one year ago marks the largest year-over-year decline in 30 years.

Rotating Equipment Expert Dr. Gary Dyson Joins The Hydro Team

Dr. Gary Dyson, Hydro Global Engineering Services

Dr. Gary Dyson, Hydro Global Engineering Services

We are pleased to announce that Dr. Gary Dyson will be joining Hydro Companies. Gary will be headquartered in the UK in our new engineering center, Hydro Global Engineering Services. This engineering center will provide the highest level of support to the Hydro network of service locations and will help solve the complex engineering problems associated with pumping equipment.

Hydro Engineering Services will provide a system that all locations can access so that we can continue to help our customers modify, upgrade and re-rate their equipment. He has expertise in hydraulic and mechanical engineering across many manufacturers and industries.

Dr. Gary Dyson has spent his entire career working with rotating equipment. He gained his PhD from Cranfield University for his work using Computational Fluid Dynamics to predict the time dependent nature of pump hydraulic performance at off-design conditions. He has used his hydraulic expertise to help many customers to re-work their equipment to improve reliability, performance and efficiency. During his time working for Clydeunion, Weir Pumps, David Brown Pumps and Mather + Platt Pumps, Dr. Dyson has developed expertise on equipment from complex multi-stage barrel pumps to single stage OH2 machines. Alongside support for Centrifugal pumps Hydro Global Engineering Services has also added expertise to support the requirements of their customers on reciprocating machines. They can advise on plunger pumps and direct acting pump repairs, upgrades and performance modifications.

 

We welcome Gary and his great wealth of experience to the Hydro team!
